3M/Littmann Electronic Stethoscope Model 3200 With Zargis Cardioscan
The stethoscope hasn’t undergone many significant breakthroughs until now. 3M’s new stethoscope listens to a patient’s heartbeat, captures the sound for later playback, lets you transmit sounds real-time to your PC, which can then be further analyzed, attached to medical records, or reviewed online with colleagues.The sound-amplifying 3M Littmann Electronic Stethoscope 3200 will not only be able to catch dangerous murmurs and heart defects but will also eliminate more than eight million unnecessary echocardiograms and cardiologist visits a year, saving some $9.4 billion. XM25 Counter Defilade Target Engagement System (i.e. The Smart Bullet)
The XM25, currently under development for the U.S. military by Alliant Tech systems, allows soldiers to measure the distance to a target using a laser range finder, dials in exactly where the bullet should explode (over or past walls, the corner of buildings) at precise distances. At a cost of $30/round, the bullets are equipped with microchips capable of registering distance according to the number of times they’ve rotated.
The Electric Eye
MIT researchers are developing a microchip that will enable a blind person to recognize faces and navigate a room without assistance, helping the blind to regain partial eyesight. The chip, which is encased in titanium to prevent water damage, will be implanted onto a patient’s eyeball. Users are required to wear special glasses fitted with a small camera that transmits images to the titanium-encased chip, which fires an electrode array under the retina that stimulates the optic nerve. The glasses will help to power the coils surrounding the eyeball.
